Description
Technical field
Present invention relates generally to the pin connectors for machine.It more particularly relates to such as Architectural Equipment, mining
The oscillation pin connector of the machine of equipment etc.
Background technique
Pin connector for machine generally falls into two classifications.Dynamic joint and static connector, in dynamic joint, structure
Component is moved relative to each other, and in static connector, structural elements does not move.When there are dynamic joint, they can come
Return is dynamic to carry out oscillating movement.Such as can it is envisioned that, this can generate friction and wear, and friction and wear may banking pin
The service life of connector.Therefore, the prior art has developed the scheme for limiting such service life rubbed and extend pin connector.
Oscillation pin connector in Architectural Equipment and winning equipment generally includes pin and matching bearing, is press-fitted into and around ties
In structure.The connector includes the intermediate structure component of commonly referred to as bear box and the outside knot on the either side of bear box
Structure component.When the connector of the cantilever crane of machine extends, bear box and outboard structure component would generally rotate relative to each other
It is a certain amount of.When the connector of machine retracts, such rotation is reversed.Therefore, these connectors have oscillating rotational motion.
Lubricant is used, usually in these connectors to reduce the service life of abrasion and extending connector.It needs to being formed in
Seam between outboard structure component and bear box is sealed, and to prevent loss of lubricant, while still being allowed in cartridge housing
Oscillating movement occurs between body and outboard structure component.Biconial sealing element is generally used in such connector, these seals with double-cone
Part uses two metal seal components being arranged symmetrically, and drives these metal seal components to be in contact with each other using elastic load ring.
However, it has been determined that such biconial sealing element more suitable for occurring continuous rotation rather than reversed or oscillation fortune in one direction
Dynamic application.
Such as can it is envisioned that, sealing element failure or the sealing element with finite lifetime may will increase and need to keep machine
Start and run required maintenance.This may cause maintenance cost and increases and lose building, the earthwork or mining effort etc.
Profit.Therefore, it may be desirable to develop a kind of more firm dynamic oscillation pin connector for machine than having imagined.
Summary of the invention
A kind of seal assembly in dynamic pin connector is provided, axial direction and radial direction are limited.Seal assembly
Including matching end face sealing ring sub-component, which includes that pairing end face seal ring element and first are negative
Ring is carried, which includes the flat seal end face radially extended and the first sizing load ring interface.
A kind of pin connector for machine is provided.Pin connector includes pin, first component, second component and seal assembly, is somebody's turn to do
Pin limits axial direction and radial direction, which limits the first sealed groove, and it is recessed which limits the second sealing
Slot, the seal assembly include pairing end face sealing ring sub-component, which is arranged in first component
In first sealed groove, and the pairing end face sealing ring sub-component includes pairing end face seal ring element and the first load ring, is somebody's turn to do
Pairing end face seal ring element includes the flat seal end face radially extended and the first sizing load ring interface.In addition, pin connector
Including lip seal ring component, which is arranged in the second sealed groove of second component, and the lip
Portion's sealing ring sub-component includes lip seal ring element and the second load ring, which includes lip seal feature
Part and the second sizing load ring interface, wherein the first component and second component rotate relative to each other, and the first load ring connects
The first sizing load ring interface of pairing end face seal ring element is closed, and second loads the second of engagement of loops lip seal ring element
Sizing load ring interface.

Specific embodiment
Now will be in detail referring to the embodiment of the present invention, example illustrates in the accompanying drawings.In a likely scenario, identical
Appended drawing reference can be used to refer to throughout the drawings same or similar component.In some cases, appended drawing reference can be in this theory
Instruction and attached drawing can be shown followed by alphabetical (such as 100a, 100b) or followed by apostrophe (for example, 100 ', 100 ") etc. in bright book
Appended drawing reference.It should be understood that indicating that these features are similarly shaped using letter or apostrophe after appended drawing reference
And have the function of it is similar, the situation being mirrored into just as usual geometry around symmetrical plane.In order in the description
It is easy to explain, letter or apostrophe are not generally included in this paper here but can be shown in the accompanying drawings, to indicate in this written explanation
The feature discussed in book repeats.
Various embodiments of the present invention provide improved edge face sealing member design.In certain embodiments of the present invention, close
The sealed lip of sealing assembly and sealing pairing end face are both reinforced by rubber load ring.This can improve each of compensation sealing component
The ability of the axial movement of a component.
In other embodiments of the invention, sealing pairing end face is discrete component, which is not integrated into such as
The biggish expensive components of bushing etc.This allows sealing pairing end face that additional feature can be used (for example, plating, coating
Or use different materials) Lai Zengqiang, it is separated with modularization and from main component.Therefore, certain sealing groups of the invention
Part can have the ability for customizing according to specific application and as needed sealing pairing face material or surface treatment.
In other embodiment of the invention, sealed lip and sealing pairing end face are greater than radially significantly
The seal assembly of the prior art.That is, radially there is the larger surface area that can be used for generating fluid-tight seal.
Therefore, when the component of seal assembly radially moves for various reasons, these seal assemblies allow improved radial direction
Motion compensation.
Referring to Fig. 1 and Fig. 2, illustrate the pin connector 200 for machine 100, wherein pin 202 limits radial R and the axial side A
